Uninvited sonics WiiM ultra into standalone dac via usb out

[Southern guy]

Streaming with WiiM ultra transport into Volumio Preciso dac using usb out , I’m getting “static like” sound emanating from the speakers - rather akin to static from newly played vinyl.
This is only apparent during data flow, disappears when music is paused and doesn’t increase or decrease with attenuation.
Fairly quiet , but insidious nonetheless .
Awaiting delivery of replacement usb (type a to b) cable and usb isolator adum3160.
Possible the Volumio or WiiM is at fault - both purchased secondhand.
Coaxial out works fine and trying different usb settings within the WiiM app hasn’t corrected the issue.
I will update when I have the cable and isolator to hand.
Any thoughts ?

dodgy USB cable is possible so the new one might sort it. Only other thing that comes to mind is some sort of incompatibility between the sample rate the USB is sending and what the DAC expects to receive. Unlikely but possible and can create weird noise.

If new cable doesn't sort it might be worth going through the menus on the Wiim and checking what USB is set to send. Should be set to automatically default but you never know. (If you didn't already do that ofc).

Thanks Martin - had been there to no avail - cable result awaits.

IMV the whole streaming thing can be a right technological ball-ache. That's one of the reasons I stick with CD. No muss, no fuss.

Agree - only went down this route initially following necessary (or so I thought) disposal of all things audio related.
Using c.d. also (Arcam cd5)
Streaming wise I wasn’t anticipating great results. Pleasantly suprised with the results here - running both sources.
Incidentally, the usb cable was defective - problem solved.

Occam's Razor for the win!
